1. A method of performing a transcervical surgical procedure in a uterus, comprising:

  • transcervically positioning an expandable support structure within the uterus using a deployment tool releasably attached to the support structure;

    expanding the support structure into a three-dimensional configuration including an upper portion and a lower portion spaced apart from the upper portion, wherein expanding the support structure delivers an expansion force against opposing walls of the uterus to thereby create a three-dimensional void within the uterus between the upper and lower portions of the expanded support structure through non-fluid mechanical distention of the uterus;

    detaching the deployment tool from the expanded support structure;

    removing the deployment tool from the uterus, leaving the expanded support structure in place;

    after removal of the deployment tool from the uterus, introducing a surgical instrument into the uterus so that a distal end of the surgical instrument is located in the void between the upper and lower portions of the expanded support structure;

    using the surgical instrument to perform a surgical procedure in the uterus by advancing the surgical instrument through an opening in the expanded support structure while the expanded support structure distends the uterus through non-fluid mechanical distention, the surgical procedure including removal of uterine wall tissue through the opening;

    removing the surgical instrument from the uterus upon completion of the surgical procedure,collapsing the support structure within the uterus after removal of the surgical instrument from the uterus; and

    removing the collapsed support structure from the uterus.
